How I easily saved at least $10,000 ... over the rest of my life

Nailed it.

We bought a set of clippers!  I have the most basic haircut in the world.  Every month I would get at least 1 or 2 haircuts at $20 a pop.  I often went to the low rent Hair Cuttery and just had some random foreign lady cut my hair.  They often did an ordinary job, but were convenient.  In our ongoing effort to cut expenses, save money, and build wealth I've decided to quit paying for mediocre haircuts and give myself mediocre haircuts for free.  We bought a set of Wahl clippers from Target for $40 bucks.  I've already cut my hair my hair twice this month, so the clippers have  paid for themselves.  The first haircut I took off a sideburn, but all in all it wasn't too bad.  The second haircut I hit my stride and gave myself a solid haircut.  My wife even helps me edge up the back.  I will cut my hair more often and always be looking fresh.

Savings (doesn't include any increases in prices and assumes I'm going to be cutting my own hair into my late 60's)

1 Hair cut a month for the next 40 years 

Total Savings: $9,600 ($20 x 12 months x 40 years)

2 cuts a month for the next 40 years

Total Savings:  $19,200 ($40 x 12 months x 40 years)

Although it will take 40 years to fully realize this savings, I would rather take my family on 2-4 really nice vacations over that period than pay some low rent barber shop $20 to $40 dollars for the rest of my life.  That money could also be used to cover 6 moths to a year worth of expenses in retirement.  This is an easy decision for me.  Cut my own hair.  Building wealth over a life time is possible for anyone.  It just takes sacrifice, time and discipline.
